Overview

Analysis reveals significant geographic variation in ADHD treatment and diagnosis among 4-17 year-olds, indicating socioeconomic factors may play a minor role.

Key Points

  • ADHD treatment prevalence varies sixfold across municipalities, ranging from 9.6 to 58 per 1,000 children.
  • Geographic variation in ADHD diagnoses mirrors medication usage, with a sevenfold increase in adolescents.
  • This register-based cross-sectional study examined ADHD patterns using data from national health registries in Denmark.
  • Significant geographic variations in ADHD treatment remain despite universal healthcare, highlighting inequities in pediatric care.
